lle it known than l, (immo: ll. Kreun', o. citizen of the .lfnited Sintes, residing nt. Seleneetndjs', eount)- of 4ehewel:t lj.' titnte of l\e'w York, have invented certain new :md

useful lmproveim-nt -I inl \`'ire-('mting )lnehinos, ol whieh the. following: is :i spot-ilimtion.

lhis im'ention rehites to deviens for insulating eleetrienl rondrit-tors :md hns vfor itsl ohjeetl the provis'ion ol n machine whereby n continuous length oll rondte-tor mo): he ront- ."ll with on insulating moteriol in o rapid :incl :it the some time thoroughly ellieient marmer.

ln my previous potente Kos. 806,574 und 806,575, l how shonn :mtl deserihed n. mne-hine for routing electriezxl eonduetors. these' patents the oven in which the insulattion is hardened is intended to he very long and open :it both ends so that the conductors simply poss through the oren :md return. ln this euse the oven is heated hf.' means of hot gosen which poss through the interior of lthe oven. l have l'onml, however, that eertom sizes of wire con he rapidly and ellieientljy rooted hy lowing the oven closed ot one end tlwrelrgsoving :i large portion of the-f heut, by prerenting` the circulation of coldv air through the oven. l have found it to advantage nlso to heut. the wells ol' the ovenJ es for instance bj; menos ol' un elet-.trie eurrent therehj. producing n very uniform temperature throogl-onty the oven.v The oven muy be ver',Y much shorter thon in the. pre viens patents nnd the temperaturer higher. l ein; thus mointnin e. high speed of insnhrf tion o?, n low expense with it groot saving` of spore lor installation.

My invention therefore consista` in the,

ment and eomhinotion of 'elements hereinafter set forth, and particularly' pointed ont in the claims annexed hereto.

Referring to the drowingsin' which 1 have shown one embodiment. of my invention, Figure 1 is a iront elevation of the upper portion of the coating machine, the oven itself notI being shown; Fig. 2 is o side. elevation of the saine; Fig. Bis an elevation partly in section of the oven itself; Figft is a. sectional features oi oontrneiion ond in the arrangeelevution of the lowerportion of the oven l showing meims'for guiding vand locking in plm-e the lower set of sheaves; Fig. 5 is a plan i view of the lower portion of the oven; Fig. 6 l is a seetion of the oven token through the l control portion thereof; Figs. 7 und S nre de-k ltnilsl'ol' the meelomismfor operating the routing rolls; und F 9 and l() ure plain and sectional views respeetively of the thermostntieindicator. Fig. 1l is ndetiiil view ot" I the lower sheuve enrrier. l ln my eti-pending application Serial No. 'l :3h-it? 1 have 'deserihed and claimed' ag pooling derive whirh is adapted. for use in' l eonreetion with the present coating device. rThe `wire. will he fed from the spooling deviee l l shenve itl', thenee over the first. of' the sheaves Il loc-ated in the oven :is hereinafter described. he. wire rtins hoek und forth over the sheaves i0 and 1l thence hack to the spooling device, in the menntime. receivin;r ithcoating of insular-tion. 'llie machineeomprises un eleetrieoll" hen-ted oven composed of n. metnllie tuhe or pipe l2 of suit-ahlesiffe. in circuit wit-h n trans ormer 13. Seeured tu und in electrical contat-.t with 'the pipe iS :t bracket 14 supported and insulated from platform 15. At the lower end of the. pipe is n conducting terminal i6 in electrical eontoet with the pipe. A series of conduct.- ing rods 17 nre arranged loneitndinally of the pipe nnd poss through brot-Kot. 14' nt the top und bracket 17', provided with a. terminal, at the bottoni. The rods ore in electrical conl tact with broek-et yllt but insulated from gliraeket, 17'; i Current. from from ln'eeket 17 through rods 17 thence boek to the pipe vto terminal 16 thereby heating the pipa` which is. completely surrounded i by n lil-.lying ol' asbestos, mineral wool or the likel ilo prevent '.ndiotion which are inside of the oven nre rotatably mounted upon a bracket 18, the hose 19 of l which is the shepe'of the oven, i. e., circulan' and snhstontiolly thesinne size so tlmtit will l mov'e freely up and down within the pipe. The bracket is support-ed by a. flexible strap or hond 20 whiel'i posses upward to the top to the iirst oi' the sheoveps l0 over the tension the transformer will pass l G5 l rl`he sheaves i l i l 35 :is for instsnoe, the top of the ove-n where the Q i y A 019.410

of the oven and thence over u band wheel or pulley 21 which is driven by a. worm and wheel 22 from any'desired source through the sheave 23. The pulley is thrown in. op-

eration by the clutch 24 to raise and lower the bracket 19. Onel of the objects of' having l the lower sheaves movable is to facilitate. the.` Stringing up of the machine when a newl siool is started or when the wire breaks. 'lhe bracket 19 supporting the sheaves isi simply brought to the top of the oven und the wn'c is pus-:ed boek um forth through the sheaves. Flu;- pipe, '.,r oven is tightly closed at the bottom by melius of n. serew enp so l, that in order to -accurately position the l bracket us it descends by gravity to the hottom of the oven und at the suine time lurking it into iosition, l provide means for mitomatienlly bringing about this risult. EX-

2-0 tending upward through the eii'p '.55 is :i pin 2G urrang'ed centrally to the oven. The upper end of the pin is pointed und adapted to engag n hole '27 in the center of the. buse il). 'llbb'rncket lll is provided with a. hood shaped portion 2S extending downward over the pin 2li. The hood is parallel with the pipe on one side, mpi-red on the other und is provided with n slot .29 having converging; sides into whit-h the pin 26 projects :is the 30 hood descends. 'lhe pin passing through the slot will turn the bracket to the desired position in which it willbe. locked by means of u spring-pressed pi 250, controlled by a. bell-crank lever 31 from some-'remote point,

operator is located.v l'lihen it. is desired to restring the` device, the lever 3l is released and 'the bracket i9 may be drown upward in; nbove described. A guide pin 32 is provided for accurately adjusting the position ',f the bracket. The ho't gitses which come 'from the oven :tre carried .oll' through the exhaust port 153. i

As a means for dcterminingdhe temperatture within the oven, Il provide u suitable indiczitor 34 which is connected with the lower end of the oven by means of n wire or other suitable connection 35. Any wellknown type of indicator or gage imiv be used, but l have shown u' simple form in which the flexible connection from the lbot- .toln of the oven passes over s. pulley 36, mid, by means of it link 37, rotates :i lever pivoted at ldiaving sit its tree end teeth 39 engaging it pinion 40. The pinion l0 rotates n pointer 41 over e, seele 42 which may be onhbruted to degrees or in any desired manner. t will be seen that the changes inv temperature affecting the length of the ipe- 12 willbe trans# mitted tothe Indicator in a very simple and rgliablemanner. I Y As a. means for'coiiting the wire; I provide coating rolls 4:3.i'md 44, which may be what .of course, that this as it leaves the hitter.
